After a long hiatus, I decided to get back into running this year and quickly discovered that the stretched-out sports bras I've had since college weren't cutting it. Every mile meant more uncomfortable bouncing and jiggling that left my boobs sore during each workout. Even after updating to what I believed were "high-impact bras" I still found myself dreading the runs I had scheduled, especially after learning about the hazards of an unsupportive workout bra.

"The breast does not contain muscle; the only two supporting structures are the skin and the Cooper's ligaments, both of which are quite weak mechanically," Jenny Burbage, a senior lecturer in biomechanics at the University of Portsmouth previously told Health. In other words, without the added support from a bra, adding pressure to the ligaments in the breast can lead to pain and sagging — two things that could deter anyone from taking on a run.

Stumped on what to buy, I consulted my twin sister, a marathon runner and U.S. Marine in training, on her favorite no-bounce sports bra. She recommended the Nike Alpha UltraBreathe High-Support Sports Bra, and it's easy to see why. Wide, adjustable straps personalize the fit and evenly distribute the weight placed on your shoulders. Plus, the bra's firm paneling and high neckline keep your breasts firmly in place. But the only way to test if it could truly stop the boob-jiggle was to wear it during a bouncy, high-intensity workout.

I first wore the bra for a weights session in the gym. While at first I found it much more constricting than my other bras, I quickly came to appreciate the extra support when I started on a round of box jumps and didn't once feel like I had to hold my boobs in place. The next day, I went for a run and felt totally secure through all five miles, to the point where I was even empowered to up my usual pace.

And while I still love my soft, comfy bras for yoga, walking, and hanging out around my house, this is the only bra I trust for high-impact exercises, and I wouldn't enjoy running half as much without it.
